Details

It was discovered that WebKit did not properly handle certain SVGPathList
data structures. If a user were tricked into viewing a malicious website,
an attacker could exploit this to execute arbitrary code with the
privileges of the user invoking the program. (CVE-2009-0945)

Several flaws were discovered in the WebKit browser and JavaScript engines.
If a user were tricked into viewing a malicious website, a remote attacker
could cause a denial of service or possibly execute arbitrary code with the
privileges of the user invoking the program. (CVE-2009-1687, CVE-2009-1690,
CVE-2009-1698, CVE-2009-1711, CVE-2009-1725)

It was discovered that WebKit did not prevent the loading of local Java
applets. If a user were tricked into viewing a malicious website,
an attacker could exploit this to execute arbitrary code with the
privileges of the user invoking the program. (CVE-2009-1712)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04

• libwebkit-1.0-1-dbg - 1.0.1-4ubuntu0.1
• libwebkit-1.0-1 - 1.0.1-4ubuntu0.1
• libwebkit-dev - 1.0.1-4ubuntu0.1

Ubuntu 8.10

changes.
